Propeller Island City Lodge is meant to be an 'aesthetic sensation for the eyes and ears'. German artist Lars Stroschen's has created a habitable work of art in the heart of Berlin that fuses innovation and pragmatism aimed to inspire guests with its ‘vision machine’. Each room is designed around a different theme to scramble the senses and perceptions. Think: fun house-come-hotel. With the likes of Sleep-in coffins for Nosferatus, a hidden attic room and even a room bathed in mystical blue light in which the double bed can be split by an illuminated barrier, the City Lodge is at the sharper end of edgy retreats.
